Underground Knowledge — A discussion group discussion

This is an odd topic but I have a problem which I can't solve on my own. I need to take 2 tests in one day. And my brain's peak performance lasts for only 1hour while the tests are approximately 4 hours. What should I do so that I have peak performance for 4hrs. Can someone suggest any good book? Any advice other than practice ?

Hi,
Well, it's not a problem, just read my new novel "How I became a human being" a memoir of an alien from Cosmos. And you will be focused on the right things for hours. No kidding, enjoy reading this fascinating story. It's available on Amazon.com
